Specific embodiment
Inventor during invention note that
With the development and change of mobile communication business demand, multiple tissues such as 3GPP all start future mobile communication system
Study new wireless communication system (i.e. 5G NR, 5Generation New RAT).In 5G NR system, an important need
, there are the transmission plans such as URLLC in Seeking Truth low time delay, highly reliable communication.The uplink scheme of URLLC, when in order to reduce
Prolong, using scheduling scheme is exempted from, in order to increase reliability, using repetition transmission plan.In the uplink scheme of URLLC, money
Source distribution is semi-statically configured using RRC or SPS (semi-persistent schedule, semi-continuous scheduling), when data reach
When time and resource allocation are inconsistent, or there is dynamic signaling, such as being used to indicate some slot is uplink, downlink, flexibly
SFI (slot-format information, time slot format information) configuration signal, Resource Properties are changed, then URLLC
Uplink will be by partial cancellation, this just will affect the reliability of data transmission, if configured using dynamic signaling additional
Resource, and have increase dynamic signaling complexity.Therefore it needs to solve semi-persistent resource in URLLC uplink scheme to match
The collision problem between Resource Properties dynamic change is set, realize reliable data transmission and reduces signalling complexity.
The data transmission scheme in URLLC is provided based on this, in the embodiment of the present invention, with reference to the accompanying drawing to the present invention
Specific embodiment be illustrated.
It in declarative procedure, will be illustrated respectively from the implementation of base station side and terminal side, then will also provide the two and match
Close the implementation for the scheme that the example implemented provides in embodiment to better understand the invention.It is such to illustrate that mode is not intended to
The two must cooperate implementation or must individually implement, in fact, also respectively being self solved when terminal and base station are performed separately
Certainly the problem of terminal side, base station side, and when the two combined use, superior technique effect can be obtained.
Fig. 1 is data transmission method implementation process diagram, as shown in the figure, comprising:
Step 101, terminal transmit data to base station by normal resource；
It when terminal transmits data to base station, is transmitted in normal resource, without using latent in step specific implementation
In resource；It for the potential resource between base station and terminal, while being the third resource between base station and other terminals, i.e. base
Dynamic dispatching stand to the resource of terminal, this resource is the most common resource type of LTE kind.
Step 102, when base station has adjusted the configuration of normal resource so that the terminal should not be used to transmit in normal resource
When data, or when the normal resource not enough completes the iterative transfer times of configuration, passed on potential resource to the base station
Transmission of data, wherein the normal resource and the potential resource are that base station is that terminal is semi-statically configured the money for being used for transmission data
Source, when and potential resource unavailable in normal resource is not used as the third resource of other terminals, base station and terminal according to
Identical mode, which determines, needs the potential resource to be used for being used for transmission data.
Wherein, the third resource refers to base station dynamic dispatching to the resource of other terminals.
For example, base station is the normal resources that terminal configures that K is used for transmission data, and configuration is N number of is used for transmission data
Potential resource, the potential resource refers to that and potential resource unavailable in normal resource is not used as the third of other terminals
When planting resource, base station and terminal are according to the determining need resource to be used for being used for transmission data of identical mode.
The resource for distributing to terminal to base station in the embodiment of the present invention has carried out priority ranking, and base station dynamic dispatching is to eventually
The resource at end is the first priority, and it is the second priority that base station, which is semi-statically configured to the resource of terminal,；In the money of the second priority
In source, priority ranking has been carried out again, and normal resource is the first priority, and potential resource is the second priority.The present invention is real
Apply the use of potential resource involved in example.The potential resource of first terminal can be the base station dynamic dispatching of second terminal to second
The resource of terminal.Terminal carries out data transmission according to priority, the first high resource of use priority, and when base station, dynamic dispatching is given
When resource, the normal resource of terminal are unavailable, for example base station is unavailable by signaling the above two resource of terminal, and
When potential resource can be used, for example the potential resource is not given resource or other ends of other terminals as base station dynamic dispatching
The normal resource at end, base station and terminal can consider automatically using potential resource.
The configuration of potential resource is usually semi-statically configured using RRC signaling to terminal by base station.Potential resource can be with
Configuration can also be configured in a resource allocation cycle across resource allocation cycle.
The use of potential resource, be usually do not need it is special signal, but group- can also be passed through
Common similar signaling is notified whether notice uses potential resource to terminal.
In implementation, the normal resource is the resource for being configured by explicit signaling and being enabled by explicit/implicit signaling.Example
Such as, normal resource is configured by DCI signaling and/or RRC signaling.The resource of normal configuration, refers to and passes through DCI
(Downlink Control Indicator, downlink control instructions) resource that modes indicate, the instruction such as dispatch, are semi-statically configured
Specific location including frequency domain and time domain relates generally to time-domain position in the embodiment of the present invention, and on different time domain position
Frequency domain position can be identical.
Potential resource on identical frequency domain position, different time domain position, specifies some time domains other than normal resource
Position, as potential resource, under normal circumstances, terminal and base station communication use normal resource, not will use potential resource, this portion
Divide potential resource that can distribute to base station and the communication of other terminals as the third resource to use, only when such as dynamic SFI signaling is drawn
Rise normal resource it is unavailable when, and terminal does not receive base station and the potential resource is distributed to other terminals as the third
Resource is in use, can just consider to carry out data transmission using the potential resource.
In specific implementation, the notice of potential resource can be implicit, be also possible to explicit；Explicit notice is i.e. logical
It crosses RRC signaling or DCI information is indicated, implicit notice can be such as: within a resource distribution period after normal resource
The N number of resource units of face followed by, for example, normal resource is K continuous slot (or mini-slot), potential resource can
To be the subsequent continuous N number of slot of this K slot.Namely:
In implementation, the potential resource is the resource enabled by explicit/implicit signal deployment, and/or automatically.
In implementation, in implicit configuration, be by within a resource distribution period normal resource followed by it is N number of
The mode of resource configures.
In specific implementation, when carrying out data transmission using potential resource, need to enable potential resource, when enabling potential resource
Two conditions are needed, first is that normal resource used in terminal and base station communication is unavailable, for example terminal receives base station sending
Dynamic SFI signaling, the signaling change the uplink and downlink attribute of normal resource, prevent terminal is carried out from reusing the normal resource
Communication；Second is that potential resource is not occupied, it is generally the case that for potential resource, the not available terminal of normal resource it is excellent
First grade is relatively high, so, if base station will occupy potential resource, need to signal the not available terminal of normal resource.
It should be noted that the resource of normal configuration is unavailable, it may be possible to because the resource of these normal configurations is again new
DCI dispatch, be semi-statically configured etc. and reconfigured, as the third resource between base station and these terminals so that
These normal resources are unavailable to this terminal, for example, original uplink slot becomes downlink by dynamic SFI signaling
Slot, then original terminal will transmit PUSCH (PhysicalUplink Shared Channel, physical uplink link sharing
Channel) time-domain resource on, terminal cannot continue transmitting for uplink PUSCH.In implementation, because signaling causes normally to provide
Source is unavailable refer to because of dynamic SFI signaling caused by normal resource it is unavailable.Meanwhile in a time window, terminal is not received
Message of the potential resource issued to base station by base station as the third resource of other terminals, referred to as terminal do not receive
Base station the potential resource is distributed to other terminals as information resources.
In specific implementation, when being transmitted using potential resource, if normal resource is K resource units, when wherein
M normal resource it is unavailable when, J is available when having in potential resource, that is, does not have the third resource as other terminals to make
With then min { M, J } a resource units of front can be used in terminal.Resource units can be subframe subframe, time slot
Slot, small time slot mini-slot etc..
It is FDM between the potential resource and the normal resource in specific implementation；
It or between the potential resource and the normal resource is TDM；
It or is between FDM, another part potential resource and normal resource between a part of potential resource and normal resource
It is TDM.
It should be noted that FDM is frequency division multiplex, it is a kind of by multichannel modulates baseband signals to different frequency carrier wave
On be overlapped the multiplexing technique to form a composite signal again；
TDM is time division multiplexing, is to be split by the time of transmission signal, it makes different signals different
Transmission, is divided into many time intervals (Time Slot, TS, also known as time slot), each timeslice for entire transmission time in time
It is occupied by signal all the way.
In the embodiment of the present invention, frequency division multiplex can be between potential resource and normal resource, be also possible to the time-division
Multiplexing, can also be it is frequency division multiplex between a part of potential resource and normal resource, the potential money of another part
It is time division multiplexing between source and normal resource.
In specific implementation, data are transmitted to base station on potential resource when terminal has been determined, then terminal is on potential resource
Before carrying out data transmission with base station, terminal can determine the potential resource of configuration by pattern, wherein the pattern
It is to be determined according to the position of the normal resource of the position and/or base station adjustment of the normal transmission chance TO of first time transmission occupancy
's.
It should be noted that pattern is the data corresponding resource sequence of TO that transmission occupies for the first time.
Specifically, the pattern can be as defined in agreement, it is also possible to base station and is allocated to terminal.
In specific implementation, on time location, between first potential resource and the normal TO that transmission occupies for the first time
Time interval is greater than K2, and the K2 is the value arranged in advance.
It should be noted that between time between first potential resource here and the normal TO that transmission occupies for the first time
Every be greater than K2 be in order to avoid base station on first potential resource dynamic dispatching others terminal.
In specific implementation, potential resource and the normal TO that transmission occupies for the first time were in the same TWG configuration period.
It should be noted that potential resource and the normal TO that transmission occupies for the first time were in the same TWG configuration period,
It is in order to avoid causing HARQ (Hybrid Automatic Repeat request, mixing is automatic repeat request) Process
The confusion of (process) ID (Identity, identification number).
The implementing procedure with terminal in conjunction with base station is illustrated the process below.
Fig. 2 is the data transmission method implementation process diagram in URLLC, as shown in the figure, comprising:
Step 201, base station configure K normal resource unit by DCI signaling and/or RRC signaling；
Step 202, base station configure by signaling or implicitly N number of potential resource unit；
Step 203, base station and terminal carry out data transmission in normal resource；
Step 204, base station change the attribute of normal resource by signaling, so that partly or entirely normal resource is unavailable；
Step 205, terminal judge which normal resource is unavailable, stop at according to the signaling for changing normal resource attribute
Data transmission in not available normal resource；
Step 206, terminal judge whether potential resource can be used according to the signaling received；
Which potential resource step 207, terminal judge such as according to not available normal resource and available potential resource
What is used；
Step 208, base station and terminal carry out data transmission on potential resource；
Step 209, base station and terminal complete the transmission of the data in entire resource period.
It is illustrated again with specific example below.
Embodiment 1
It according to current standard, is configured by RRC, K=4, RV={ 0303 }, time-domain resource position is { starting OFDM
Symbol, OFDM symbol number }, this time-domain resource position is defined as a transmission opportunity TO, that is, completes primary repetition transmission
Resource, K=4 mean to carry out four repetition transmission, need four TO.Here TO is usually continuous.
Consider the upstream data packet of UE (User Equipment, user equipment) in a TWG (transmission
Without grant, exempts from scheduled transmission) after first TO in the configuration period, reach before third TO, then UE will be in third
The PUSCH of a TO transmission RV=0, the PUSCH that RV=3 is transmitted in the 4th TO, according to present standard, in this resource period
Other transmission will no longer be carried out.Base station blind examination PUSCH, under normal circumstances, it should be detected not in third TO and the 4th TO
With the PUSCH of RV.
Assuming that base station will explicitly or implicitly notify terminal there are also time resource in the TWG configuration period, which resource can be with
It is configured as potential TO, potential TO means and will not be used under normal conditions that only normal TO in front cannot make
It uses, the situation that potential TO is not determined as the third resource of other terminals and base station and terminal according to identical mode
Under, that is, base station and terminal can know and use, know how in the case where using, and could be used.

Transmitting uplink data is carried out with other terminals.If base station do want to occupy first and second potential TO to other terminals into
Row transmitting uplink data, then needing to notify terminal that cannot use potential resource using dynamic signaling, because of these potential resources
Used as the information resources of other terminals.
Under normal conditions, terminal transmits first PUSCH, in the 4th TO transmission second in the normal TO of third
After PUSCH, the RV=0 and RV=3 of first and second potential TO transmission PUSCH will use.
Embodiment 2
It according to current standard, is configured by RRC, K=4, RV={ 0303 }, time-domain resource position is { starting OFDM
Symbol, OFDM symbol number }, this time-domain resource position is defined as a transmission opportunity TO, that is, completes primary repetition transmission
Resource, K=4 mean to carry out four repetition transmission, need four TO.Here TO is usually continuous.
Consider the PUSCH of first normal TO transmission RV=0 of the upstream data packet of terminal within a TWG configuration period
Afterwards, dynamic SFI configuration information is received, so that several subsequent normal TO can not be reused, for example latter two normal TO can not
It uses, then terminal will be after first normal TO, second normal TO transfer PUSCH, in the normal TO of third, the 4th
A normal TO will be transmitted no longer in this resource period according to present standard.Base station blind examination PUSCH, normal condition
Under, it should the PUSCH on first TO and second TO of blind examination.
Assuming that base station will explicitly or implicitly notify terminal there are also time resource in the TWG configuration period, which resource can be with
It is configured as potential TO, potential TO means and will not be used under normal conditions that only normal TO in front cannot make
It uses, the situation that potential TO is not determined as the third resource of other terminals and base station and terminal according to identical mode
Under, that is, base station and terminal can know and use, know how in the case where using, and could be used.
Base station configurating terminal, behind normal TO, continuous N number of TO is potential resource.
Base station is in first normal TO blind examination to PUSCH, while according to dynamic SFI signaling, terminal will be normal at first
After TO, second normal TO transfer PUSCH, it will know simultaneously without transmission in the normal TO of third, in the 4th normal TO
Road terminal can continue to transmit PUSCH at first and second potential TO, therefore base station cannot be in the terminal under normal conditions
Other terminals are called to carry out transmitting uplink data on the time-domain position of first and second potential TO.If base station does want to account for
Transmitting uplink data is carried out to other terminals with first and second potential TO, then needing to notify terminal using dynamic signaling
Potential resource cannot be used, because these potential resources have been used as the information resources of other terminals to use.
Under normal conditions, terminal transmits first PUSCH, in second TO transmission second in first normal TO
After PUSCH, the normal TO of third, the 4th normal TO will be without transmission, and use first and second potential TO

Embodiment 3
According to current standard, when terminal transmits data to base station, base station is that terminal configures resource, time domain money by RRC
Source position is { starting OFDM symbol, continuous OFDM symbol number }；Frequency domain resource position be according to type (type) 0 or
PRB (Physical Resource Block, the Physical Resource Block) set that the mode of type1 is distributed.
Time-domain resource position and frequency domain resource position are defined as a transmission opportunity TO, that is, complete primary repetition and transmit, than
Such as K=4, RV={ 0303 }, it is meant that 4 repetitions of Yao Jinhang are transmitted, and 4 TO are needed.Here TO is typically occurred in continuously
K time slot on.
If there is 4 normal TO within a TWG configuration period, the upstream data packet of terminal is within the TWG configuration period
First TO after, reach before third TO, then terminal will transmit the PUSCH of RV=0, by the 4th by third TO
The PUSCH of TO transmission RV=3 will no longer carry out other data transmission according to present standard.Base station blind examination PUSCH, positive reason
Under condition, it should detect the PUSCH of different RV in third TO and the 4th TO.
Assuming that there are also time-frequency domain resources after third TO in the TWG configuration period, these time-frequency domain resources may be different
In the time-frequency domain resources configured before, if frequency domain position is different and/or time-domain position is different, base station will be by explicit or implicit
Mode notify terminal, which resource could be configured as potential resource, can be by latent after terminal receives the notice of base station
Carry out data transmission in resource.
Wherein, potential resource means and will not be used under normal conditions that only normal resource in front cannot make
With and base station and terminal determined according to identical mode in the case where needing use, the resource that could be used.
With reference to the accompanying drawing to being that FDM is illustrated between potential resource and normal resource.
As shown in figure 3, being FDM between potential resource of the embodiment of the present invention and normal resource.There are 4 normal TO in Fig. 3,
Respectively TO0, TO1, TO2 and TO3 have 2 potential TO, respectively Top and TOq.
From figure 3, it can be seen that first potential resource, that is, Top time location appear in normal TO2 after,
Frequency domain position is different from the frequency domain position of normal TO, that is to say, that potential resource is FDM with configuration resource (normal TO).
Since the upstream data packet of terminal reaches after the normal TO1 in a TWG configuration period, before normal TO2, then eventually
End by normal TO2 to base station transmission data, base station at normal TO2 blind examination to PUSCH, it is determined that terminal can be by potential
TOp and potential TOq continues to transmit PUSCH.
Since terminal can transmit data by potential TOp and potential TOq, base station cannot be in the terminal under normal conditions
Potential TOp and potential TOq time-frequency domain resources position on call other terminals carry out transmitting uplink data.If base station is necessary
It occupies potential TOp and potential TOq and carries out transmitting uplink data to other terminals, then needing to notify terminal using dynamic signaling
It cannot be carried out data transmission using potential resource.
Under normal conditions, terminal transmits first PUSCH, after normal TO3 transmits second PUSCH in normal TO2, meeting
Third PUSCH and the 4th PUSCH, respectively RV=0 and RV=3 are transmitted using potential TOp and potential TOq.
Embodiment 4
According to current standard, when terminal transmits data to base station, base station is that terminal configures resource, time domain money by RRC
Source position is { starting OFDM symbol, continuous OFDM symbol number }；Frequency domain resource position is according to 1 side of type 0 or type
The PRB set of formula distribution.
Time-domain resource position and frequency domain resource position are defined as a transmission opportunity TO, that is, complete primary repetition and transmit, than
Such as K=4, RV={ 0000 }, it is meant that 4 repetitions of Yao Jinhang are transmitted, and 4 TO are needed.Here TO is typically occurred in continuously
K time slot on.
If different moments of the upstream data packet of terminal within a TWG configuration period reach, terminal will be not
First time PUSCH is transmitted on same TO, the number of actual transmissions is related with the TO that first time transmission occupies, as shown in 4 figures.
In Fig. 4, if the TO that transmission occupies for the first time is the 1st TO, the number of actual transmissions data is 4 times；If
The TO that transmission occupies for the first time is the 2nd TO, then the number of actual transmissions data is 3 times；If the TO that transmission occupies for the first time
For the 3rd TO, then the number of actual transmissions data is 2 times；If the TO that transmission occupies for the first time is the 4th TO, practical to pass
The number of transmission of data is 1 time.
According to present standard, when terminal transmits data to base station, will no longer be carried out in other resources outside normal TO
Other transmission.Base station blind examination PUSCH.
Assuming that there are also available time-frequency domain resources after the TO that first time transmission occupies in the TWG configuration period, at these
In time-frequency domain resources, explicit or implicit notice which resource of terminal could be configured as potential potential resource, terminal by base station
After the notice for receiving base station, it can be carried out data transmission by potential resource.
Wherein, potential resource means and will not be used in general that only normal resource in front cannot
Using and base station and terminal determined according to identical mode in the case where needing use, the resource that could be used.
When base station is that terminal configures resource, as shown in figure 5, base station is that terminal is being configured with 4 just within a configuration period
Normal TO, 5 potential TO.4 normal TO are respectively TO0, TO1, TO2, TO3,5 potential TO, respectively TOl, TOp, TOq, TOk
And TOs.
When reaching different moments of the upstream data packet of terminal within TWG configuration period, base station is first according to the
The TO that primary transmission occupies, determines the time-frequency domain position of occupied normal resource and potential resource, then traverses all possibility
The TO that occupies of first time transmission, the pattern of a resource occupation is obtained, in the pattern of the resource occupation, both comprising just
Chang Ziyuan, and include potential resource, as shown in table 2, secondary series and third column in table 2 are respectively pattern 1 and pattern
2。
Table 2
In table 2, for example first occupied TO is TO0, then base station, which determines, does not use potential resource, obtains a money
The pattern1 that source occupies is { TO0, TO1, TO2, TO3 }, and the pattern2 of resource occupation is { TO0, TO1, TO2, TO3 }.
In table 2, for example first occupied TO is TO1, then base station, which determines, uses a potential resource, obtains one
The pattern1 of resource occupation is { TO1, TO2, TO3, TOk }, and the pattern2 of resource occupation is { TO1, TO2, TO3, TOq }.
It should be noted that the TO q2, TO q3 in table 2 are not embodied in Fig. 5, it is believed that TO q2 and TO
Q3 is the TO of the different frequency domain positions on the same time location of TO q.
In table 2, the pattern of other resource occupation can also be further increased, including the different potential resource of selection, no
With potential resource put in order etc., a new pattern can be formed.
So when reaching different moments of the upstream data packet of terminal within a TWG configuration period, as long as base station allows
Which pattern is terminal know that with, terminal carries out data transmission according to the TO in pattern.
Terminal knows carry out data transmission using which pattern, and base station can notify (to compile to terminal patternindex
Number), so that terminal is determined the pattern of transmission data according to pattern index；Base station can also fix selection one
Pattern1 in pattern, such as table 2, terminal select pattern1 to carry out data transmission every time.
Embodiment 5

Source position is { starting OFDM symbol, continuous OFDM symbol number }, and frequency domain resource position is according to type's 0 or type 1
The PRB set that mode is distributed.
Time-domain resource position and frequency domain resource position are defined as a TO, that is, complete primary repetition and transmit, such as K=4, RV
={ 0000 }, it is meant that 4 repetitions of Yao Jinhang are transmitted, and 4 TO are needed.Here TO typically occurs in continuous K time slot
On.
If different moments of the upstream data packet of terminal within a TWG configuration period reach, terminal will be not
First time PUSCH is transmitted on same TO, the number of actual transmissions is related with the TO that first time transmission occupies, as shown in Figure 4.
According to present standard, when terminal transmits data to base station, will no longer be carried out in other resources outside normal TO
Other transmission；If carried out data transmission using potential resource, terminal just can know which will be used after first time transmits
A little potential resources carry out data transmission.
Base station on the TO that first time transmission occupies after blind examination to PUSCH, can according to pattern predetermined or
The potential resource of configuration determines which potential resource the transmission of SS later will use, and base station is not capable of calling it under normal conditions
He carries out transmitting uplink data at terminal on these potential resources, to avoid the interference between user.If base station has to occupy
Terminal needs potential TO to be used to carry out transmitting uplink data to other terminals, then needs to notify that terminal cannot using dynamic signaling
Use the potential resource.
Since base station uses the time-frequency domain resources comprising potential resource using dynamic dispatching terminal, so base station needed at end
End for the first time enable potential resource before the time greater than Kx in know that terminal will enable the potential resource, therefore, when
Between on position, the time interval between first potential resource and the normal TO that transmission occupies for the first time has to be larger than Kx, to keep away
Exempt from base station other terminals of dynamic dispatching on first potential resource, Kx here is the value arranged in advance.
